Wow! Such a good movie.

It's a mild crowd pleaser for people who are exhausted by blockbusters.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.
